Hi Ferret, there's a lot of great stuff here, thanks! My 1976 CB750F (still own it) head shakes at exactly 47 mph on deceleration if you take your hands off the handlebars. (At least it did 10 years ago, the last time I rode it). I'm sure the front wheel was never balanced properly, and the steering head bearings are probably worn also. The races on my 1998 VFR steering head bearings wore out and I replaced them (little indentations caused by the balls in both the upper and lower), but this bike never shook the handlebars.
